Warehouses are a type of Ageless Building in Civilization 7, which permanently increase the tile yield of specific tiles when constructed and take up a slot in a district. Building them early will give you a huge resource boost over time, but you'll need to position them carefully to leave room for other construction down the line, since they never become obsolete and can never be overbuilt.

Other Ageless Buildings, such as many of the Civilization-specific buildings, will offer powerful benefits from the time you can build them to the end of your playthrough in Civilization 7, so it's useful to know what ageless buildings exist and how they work.

All Ageless Buildings (Except Warehouses)

Civ 7_Meiji Japan Overview

All the other Ageless buildings are unique to specific civilizations and may only be constructed while you're playing as that civilization. Once they're built, however, they will continue functioning with adjacency bonuses intact for the remainder of the playthrough and continue to offer their bonuses in later ages.

Unless the effect is instantaneous on completion of the quarter, all effects of quarters formed by these buildings will also continue to function in later ages. Generally speaking, if a building is exclusive to a specific civilization, it will be treated as ageless.
